SPECIFICATION.

- 1, WILLIAM H. SAUNDERS, of the county of Garroll and State of Tennessee, have invented a certain composition of metals called Saunders anti-friction metal, to be used in the by foundrymen,-( in ade by fusing together about one part iron filings, one part resin, two parts tar, and oneffourth of a part glass, by weight,) about one part; of zinc about one part; of antimony, tivo parts; and of lead fourteen parts; fuse and mold into an y required design or form. This alloy, when applied to the bearings of .machinery in the form of boxes, bushings,

platings, or any other form in which Babbitt or other like metal is commonly used, will greatly tend to relieve friction, consequently to avoid heat and wearing, and on account of its great tenacity will not easily break.
